The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases tranquil operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security in accordance with protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact match. And the tighter suit means less play in the gear teeth, which may be the trigger of backlash to begin with. Of course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for instance, some equipment types such as strain wave gears, or harmonic gear drives, have zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque ideals, the input stage is certainly dimensionally smaller than the output stage. Its short style makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it an ideal fit for highly powerful applications where highest positioning and rate accuracy is required. The flange output generates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB series; the right angle shape makes the GSBL series an ideal match for all powerful applications where space is limited.
